Shape memory insulators comprising a first layer of core material, such as polymeric insulative material, and a second, shape memory layer of elastomeric material, for attachment to objects. The shape memory layer may comprise silicone rubber, silicone gum, silicon crepe, and/or silicone gel, for example. The shape memory insulator may be part of a handle for an object, such as a pot or pan, for example, or other objects and devices requiring continuous and/or repetitive manual operation. The shape memory polymeric material may conform to the shape of the user's hand when the handle is gripped by a user's hand. When the grip is released, the shape memory material returns to its original shape. The shape memory insulators provide insulation as well as improving comfort and/or control over the engagement and use of objects, while decreasing arm and hand wear and/or strain of those using the objects.
